Adult Sheldon: Grown-ups and the elderly had always liked me, and now I had won over undergrads. Like a beloved board game, I'm fun for ages nine to 90.

Adult Sheldon: I didn't realize until years later that my father was only asking questions about lightning and thunder to cheer me up. In fact, he would often pretend to be dumb just to make me feel better.

Adult Sheldon: My father didn't always get the credit he deserved. The advice he gave me actually worked out pretty well. Of course, I never told him.
George Sr.: Talked to Billy.
Missy: Why would you do that?
George Sr.: No, it was good.
Missy: Stay out of my life.
Adult Sheldon: He may not have been the world's greatest dad. But maybe we weren't the world's greatest kids.

Adult Sheldon: Visiting Tam's house for the first time was an emotional roller coaster.
For example, it's traditional in Vietnamese homes to have gruesome religious iconography near the entrance. I did not like that.
However, it's also customary to not wear shoes around the house for sanitary reasons. I did like that.
Interestingly, one of the main ingredients in Vietnamese cooking is an extremely pungent condiment known as fish sauce. I did not like that.
But before every meal, it's common for everyone to wash their hands and face. I did like that.
Forks are not customary in a Vietnamese household. I did not like that.
And instead of napkins, there was one towel for everyone to share at the table. Seriously, what are they thinking?

Mary: What is going on? Sheldon, are you okay?
Sheldon: My stomach hurts.
Darren: He's gonna throw up.
Mary: Did you give him beer? Did they give you beer?!
[Mary follows Sheldon, Darren and Oscar into the dorm room]
Sheldon: Just root beer.
Mary: It's gonna be okay, baby. [Sheldon throws up] Oh. Why is it so colorful?
Sheldon: Too many... [gags] Skittles. [retches]

George Sr.: Where's the coffee?
George Jr.: I finished it.
George Sr.: When you finish a pot, you're supposed to make more.
Mary: Oh, is that the rule?
George Sr.: It is for him. Why are you reading my paper?
George Jr.: Well, pardon me for keeping up on events of the day.
George Sr.: Tomorrow's headline: Father Strangles Son.
George Jr.: Good luck. My horoscope says "things are looking up."

Mary: You did not just tell our son that he could stay the night by himself.
George Sr.: The campus is safe, and he's not by himself, he's with friends.
Mary: Friends that we don't know. What if there is alcohol?
George Sr.: Then they're gonna get a lot of fun facts about the history of fermented beverages.
Mary: I am serious.
George Sr.: So am I. How else would I know that monkeys get drunk by eating rotten fruit off the jungle floor?
Mary: He is not ready for this kind of situation.
George Sr.: Mary, he's a good kid. He's not gonna drink anything he shouldn't. And if he cared about peer pressure, he wouldn't wear a bow tie.
